Interesting. So, according to the post, “Morning Rituals That Are Making You Look Older, What Do You Think?” True or False, drinking caffeinated coffee or caffeine can dehydrate you, your skin. So directly applying a caffeinated product can hydrate your skin?
Yes, it seems like that’s what the article was saying.
Emmetsberger said “Basically, the skin can act as a battery, and by changing the electrical properties of it, we can enhance hydration. What we’ve found is caffeine actually increases the skin’s electrical properties, or electrical potential, which is directly correlated with an increase in the skin’s water content.”
Oral consumption of caffeine is dehydrating (it’s a diuretic), but a topical application won’t dehydrate you.
